Given numbers are 803, 930, 945, 661
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(803, 930) = 746790
GCD(803, 930) = ( 803 x 930 ) / 746790
= 803 / 930
= 803
Step2:
LCM(1, 945) = 945
GCD(1, 945) = ( 1 x 945 ) / 945
= 1 / 945
= 1
Step3:
LCM(1, 661) = 661
GCD(1, 661) = ( 1 x 661 ) / 661
= 1 / 661
= 1
So, Greatest Common Divisor of 803, 930, 945, 661 is 1
